The answer is still build more (which you basically admit yourself in your first sentence). Homes skew larger and more expensive precisely because it's so hard to build them so developers need to make more money from each one. The fixed costs per unit are too high, so the ones that need to be lowered or eliminated should be. That will incentive building more units not just more expensive units. You'd see a lot more 1…
Build Moar seems to be too simplistic. There's just too much demand and too much investment capital seeking profit. No matter how much you build, most of the housing supply is going to get sponged up by investors, landlords, and private equity, and the price isn't going to go down. You'd probably have to 4X to 5X the current housing supply to make a dent in prices.
To earn a return through renting or appreciation. If there are more houses than buyers returns drop.

So do that.
